摘　　要：为探索生物质燃料烟叶密集烘烤碳排放强度及排放规律,优选合理的生物质燃料形式及供热设备,分析其减排潜力,对3种生物质供热设备进行烘烤对比试验,采用碳排放因子和质量平衡相结合的方法分析其碳排放特性;并应用草谷比法测算烟秆生物质替代燃煤密集烘烤的供热潜力。结果表明,生物质碎片燃料外置式供热设备、生物质颗粒燃料外置式供热设备、生物质颗粒燃料内置式供热设备烘烤烟叶的单位干烟叶碳排放量分别为1.94、2.09和2.05 kg CO_(2)/kg干烟叶,三者电能消耗产生的间接碳排放量占其总排放量的百分比分别为11.4%、11.5%和12.3%。烟秆生物质收集加工用于烟叶烘烤可提供不低于82.9%的烟叶烘烤用能,供能潜力大。以燃煤烟叶烘烤为参照,生物质碎片燃料外置式供热设备、生物质颗粒燃料外置式供热设备及生物质颗粒燃料内置式供热设备的二氧化碳减排量分别为29.9%、24.5%和26.0%。因此,生物质燃料供热设备减排性能优良,是较为适宜的烟叶密集烘烤热源。To investigate the carbon emission intensity and regularity of biomass fuel for bulk curing of tobacco leaves,reasonable biomass fuel forms and heater types were selected,and the carbon emission levels and reduction potential were analyzed.Comparative experiments were conducted among three types of heaters using the biomass fuel.The carbon emission characteristics were analyzed using carbon emission factor and mass balance method.The grain-to-straw ratio was used to measure the heating potential of the bulk curing with tobacco stalk biomass instead of coal.The results showed that the carbon emissions per unit of dry tobacco leaves for external heating with biomass chips and biomass pellets,and internal heating with biomass pellets were 1.94,2.09,and 2.05 kg CO_(2)/kg dry tobacco leaves,respectively.Indirect carbon emissions from electricity consumption of the three types of heaters accounted for 11.4%,11.5%,and 12.3%of the total emissions,respectively.The use of collected and processed tobacco stalk biomass for curing could provide no less than 82.9%of the total energy consumption,which was a significant energy supply potential.Taking coal-fired tobacco curing as a reference,the emission reduction of the above three types of heaters was 29.9%,24.5%,and 26.0%,respectively.The biomass fuel-fired heaters have excellent emission reduction performance and can be more suitable heat sources for bulk curing of tobacco leaves.
